Assume an AWGN channel with two-sided noise power spectral density $\frac{N_o}{2}= 0.5 \times 10^{-12}$ W/Hz. Using an optimal receiver and the relation $Q(v)= \frac{1}{\sqrt{2\pi }}\int ^{\infty }_{v} e^{-u^2/2} \: du,$ the bit error probability for a data rate of $500$ kbps is $Q(2)$ $Q(2\sqrt{2})$ $Q(4)$ $Q(4\sqrt{2})$ Communications gate2014-ec-2 analog-communications frequency-shift-keying + – Milicevic3306 464 views answer comment Share Follow Add Sync Questions Print 0 reply Please log in or register to add a comment.
